The Prague meetingThe ISO SC34 meeting in Prague was a big affair with five different working groups and many attendees. Working group 3 had a lower attendance than usual (for a number of reasons), and perhaps for that very reason had a highly productive three days focusing on TMCL. The status before the meeting was that we have a quite loose draft that shows in rough outline the intended functionality of the language and gives a good indication of the way it's intended to be specified. The task of the meeting was to process this to the point where the editors could write something quite close to the final specification. I'm happy to say I think that's what we did. ...

Many Topic Maps protocols have been presented already, mostly similar in conception, but TMShare is actually a completely new kind of protocol. Unlike earlier proposals it does not allow random access to topic maps on the server, but instead provides a feed of the changes to those topic maps. So essentially it provides a mechanism to replicate a topic map or part of one to another server. (I call this TMShare the Second because there was another TMShare protocol before this one.) ...

The site in question is, of course, Topic Maps-driven, and so it has, of course, topic pages for the people who created the tools. Those pages inevitably become pretty boring, because the tools site isn't the place to collect lots and lots of information about people. ...

This is essentially a graphical modelling tool based on the initial GTM level 1 proposal. His idea is that it will let users graphically model their ontologies, and be able to import and export them to TMCL. ...

This proposal was born out of his experiences with drawing Topic Maps examples in discussions with his colleagues, where he got fed up with confusion over what the drawings were meant to show. His presentation is essentially a private proposal for GTM level 0. ...

The first thing to note is that TMCL is firmly meant for validation, and not for reasoning. In other words, TMCL is a schema language, rather like DTDs, RELAX-NG, XSD, EXPRESS, SQL DDL, and so on, but one specifically designed for Topic Maps. Note: this has been updated to the latest 2009-06-16 draft. ...

Writing a sudoku solver, however, sounded like it might be fun. And, so, since I had nothing better to do I decided to give it a shot. ... Read | 2008-09-10 16:40 | 12 comment(s) A CTM tutorialThe new compact textual syntax for Topic Maps being standardized by ISO, CTM, is now approaching stability, and so I thought it would be good to provide a little tutorial on it to show people what the syntax looks like in the current draft. With a little luck we might even get some feedback, which would be nice. ... Read | 2008-08-31 15:02 | 1 comment(s) Topic Maps, RDF, semantics, merging ...Michael Sperberg-McQueen wrote a blog post on RDF and Topic Maps where he brought up some interesting questions. I started trying to reply in a comment on his blog, but after writing two full pages I decided to instead turn it into a blog posting here. ... Read | 2008-07-29 16:54 | 1 comment(s) Finally solving the performance problemI wrote about the performance problems the tmphoto application had suffered from, and my failed attempts to fix them. I decided that the problem was that I'd set out to solve the problems without really knowing what the cause was, since reducing traffic by 55% obviously wasn't going to rescue the site. So the solution must be to do some proper research first, and then try to solve it. ... Read | 2008-07-06 14:49 | 1 comment(s) |
